The five-round main event at Bankers Life Fieldhouse in Indianapolis will take place on Aug. 28. Tickets go on sale June 14.

This is a rematch of an April 2009 fight that Kampmann won via a split decision.

"He’s going to have his rematch," Kampmann told FOXSports.com. "It’s going to be a different fight. I’m a different fighter. He’s a different fighter. We had a good scrap last time, and this time it’ll be five rounds. That’ll give me plenty of time to get the finish."

Condit (28-7), the No. 2 contender in UFC’s official rankings, is coming off two losses, albeit by decisions in close fights against welterweight champ Georges St-Pierre and top contender Johny Hendricks.

Kampmann (20-6) is ranked as the No. 7 contender. In his last fight, Kampmann was knocked out by Hendricks in the first round last November.

FOX Sports 1 debuts Aug. 17 and will feature a major UFC card in Boston. The headliner for that event has not been announced.
